Answer:
4
Step-by-step explanation:
Answer:
a) 
b) 
Step-by-step explanation:
a) Let the required polynomial be p(x).
We have the relation, 
+ p(x) = 18
i.e. p(x) = 18
i.e. p(x) =
b) Let the required polynomial be q(x).
We have the relation, + q(x) = 0
i.e. q(x) = 0
i.e. q(x) =
While “digital” commonly refers to electronics in general, the scientific definition of digital is much different. “Digital” in information science refers to the finite, discontinuous phenomenon (e.g., on or off states in a light bulb) as opposed to infinitely varying, continuous analog phenomenon (e.g., the brightness of daylight). It can also refer to representing data in figures as opposed to data represented in pictorial form.
Answer:
About 16 years
Step-by-step explanation:
First we need to figure out 5.25% of 12000
5.25 x 0.12000 = 0.63
Then we move the decimal
630
Then we need to figure out how many years it will take to reach $22000
Since we already owe $12000, we can just divide using $10000 because 10000 + 12000 = 22000
10000/630 = 15.87
Which is about 16 years
Answer: Alvin = 42 yrs , Elga = 21 yrs
Step-by-step explanation:
Let Elga's age be x , and Alvin's age be y ,since Alvin is two times Elga's age , then
Alvin's age = 2x , that is
y = 2x ............... equation 1
The sum of their ages is 63 implies
x + y = 63 .............. equation 2
Solving the resulting linear equations by substitution method.
Substitute equation 1 into equation 2 , we have
x + 2x = 63
3x = 63
x = 63/3
x = 21
Therefore : Elga is 21 years old , then Alvin will be 21 x 2, which will be 42
